A Ponteland group is calling on fellow residents to make their feelings known about plans to re-locate the library to the leisure centre.
Northumberland County Council unveiled details about the move earlier this month. It is set to take place in spring 2016.
The authority says the measure is part of the need to make savings and it has successfully integrated library and customer facilities in various towns.
It also revealed further information this week about how the new arrangements will work, including that the services will be accommodated within the existing crèche area and additional space in the wider building will be utilised.
But this has not impressed the group of residents who believe the areas of the leisure centre that will take on library services are not fit for purpose.
Under the heading Save Ponteland Library Now, a spokeswoman for the group said: “The library is an essential service well used by Ponteland people, which we do not want moved.
“If the re-location goes ahead as planned, it will considerably reduce the offering of books and other library services.
“What costings have been done for the necessary alteration of the premises and improved access?”
Those against the move are asked to write to Nigel Walsh at County Hall or email firstname.lastname@example.org
A county council spokesman said that customers will be able to access library resources seven days a week, as opposed to five days a week at the moment, and there will be more customer-staff contact time as a result of new staffing arrangements.
